The tissues of your respiratory tract (including your nose) become filled with fluid. The tissues do this in response to the invasion of that darn cold virus. This called an immune response. You can take decongestants to help until your body gets rid of the virus. That can take 7-10 days.
when i have a cold, it is hard for me to breathe. i don't have much energy. why do you think this happen
I think it is 'Can't breathe laughing so hard'!
Because you have a stuffy nose when you get a cold.
yes
because its hard to breathe thin air above earths surface, the higher you go its hard to breathe oxygen.
It is very hard to breathe underwater without assistance from an air tank.
you will have amnesia
because the air is thinner the higher the altitude is.
Hard to take in air
because you get really nervous and you kind of just breathe hard or blush it happens to everyone
It is hard to breathe when you laugh out loud because you used most of you breathe to laugh as hard as you did. Try to get someone to make you laugh. Then see how long it takes you to catch your breathe...
To be honest i have no idea! I only think tht they grow in cold areas because the cold makes them more juicer, where the sun makes them hard and dry... that's only wat i think
